COMBINATION-LOCK.

Application filed December 26, 1916, Serial No. 138,695.

To all whom it may concern.'

Be it known that I, CLARENCE E. ANABLE, a citizen of the United States, residing at Sacramento, in the county of Sacramento, State of California, have invented certain new and useful Improvements in Combination-Locks; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form apart of this application.

This invention relates to improvements in combination locks, used in connection with stop thief devices for preventing the theft of automobiles or automobile parts or accessories. The object of the invention being to produce a combination lock having a simple combination and one which operates by the sense of touch rather than by a dial orV similar contrivances commonly used in connection with the present day forms of combination locks. By reason of such form of lock it will be almost impossible for any person not acquainted with the particular combination to unlock, pick or work the same successfully.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for Athe purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a sectional view of'theplock as it would appear when applied for the purpose of locking the steering post of an automobile.

Fig. 2 is a. sectional view of the lock taken on a line X-X of the Fig. 1, with the spring removed.V

numeral 1 designates casing of the lock which 1s substantially cylindrical in cross section. The numeral 2 designates the` tector 2.Y The detector 2 is provided with a central orifice 7 through which is movably7 disposed a lock pin 8.` Cn this pin 8 is a projecting finger member 9 which, when the combination is inv unlocked position, fits into the recess 6.

Turnably disposed around the detector 2 are two combination disks 10 and 11 each turnable within the other. These disks are provided with .recesses 12 and 13 respectively arranged to be on a line with the recess 6 when the lock is in unlocked position. The disks 10 and 11 are held in proper position by means of av spiralspring 1/1 interposed between such disks and a retaining plate 15 mounted within the casing 1. When in unlocked position the pin 9 is held within the recessesr6, 12'and 13 by means of a spring 16 mounted around the pin 8 and bearing between the plate 15 and a washer 17, on such pin 8 the action of which spring against said washer being such as to force the finger member 9 into the said recesses. On the outside of the casing 1 the pin 8 is 'provided Vwith an operating knob 18.

When the parts are in unlocked Yposition as shown in Fig. 1 they Vmay be held in such position by means of 'a nger member 19 engaged undera collar 2O on the member 18.

This enger member 19 ie ehehe ende 21 mounted for ymovement on the upper side of the casing 1 and provided with an operating nger member 22. In the side-of the slide 21 are two notches 23 and 24 respectively arranged to be engaged by a spring member 25 which is fixed to the side of the casing 1. `Whenj this spring member 25 is engaged with the notch 24 it holds the finger member 19 under the collar 20 and thus maintains the pin 8 inunlocked position. When the spring 25 is in engagement with the notchV 23 the finger member 19 is held out .of engagement with the collar 20'l and the knob -18 may then be used towork the Y combination and throw the pin 8 into locked position as is found desirable.

The operation of the lock is as follows:

Assuming the same to be in unlocked position as shown in Fig. 1 the operator grasps the member 18 and presses the pin 8 downwardly. This clears the finger member 9 out of the recesses 6, 12 and 13 and leaves it free to be turned into the notches 4. l/Vhen this is done the pin 8 is held in its lowest position which is its locked position. In the adaptation shown in F ig. 1 it locks the steering post 26 from turning within steering sleeve 27. It can well be seen however, that it can be used equally well to lock any two members in fixed position with respect to each other.

lhen turned into engagement with the notches 4 the finger member 9 of course, engages the combination pin 28 on the disk 1l and the pins 29 and 30 on the disk 10 and moves such disks so that the recesses 6, 12 and 13 are moved out of register with each other.

Then when it is desired to release the lock again the member 18 is operated to turn the pin 8 until the linger member 9 moves to the blank space 5. In moving through the blank space 5 there will of course be no clicking sound. Hence, this point is the point of beginning to operate the combination. The said finger member 9, is of course, held in frictional engagement with the detector 2 and its notches 4 by means of the spring 16 so when such member 9 is moved over the notches 4 it will make a clicking sound, one for each notch. This then is the.

means of detecting and counting the com bination. As the finger member 9 moves over these notches 4 it engages the pins 28, 29 and 30 in a corresponding manner to line up the disks 10 and 1l to bring the recesses 6, 12 and 13 into register with each other.

The combination set forth in Fig. 2 is as follows:

Commencing at the space 5, count one click to the left, move back to the space 5. Then count two clicks to the right, then move back to the space 5. lVith the first movement to the left the member 9 engages the pins 29 and 28 and lines them together and brings the recesses 13 into a line with the recess 6. Then with movement back to the space 5 and two clicks to the right the member 9 engages the pin 30 and moves it so as to bring the recesses 12 into register with both of the recesses 6 and 13. Then when the linger member 9 is turned back it is free to move into the recesses 6, 12 and 13 into which it is thenv forced by the spring 16. This action moves the pin 8 out of its locking position.

In Figs. 4 and 5 I show the application of my improved notched combination detector used on an automobile robe lock. In this form of construction there are two arms 31 and 32 arranged to be closed in on the robe and locked over some part of the automobile. My improved combination lock is applied to these rods by means of the following structure, namely:

The arm 32 is connected with an annular casing 33, turnable in which is a ring 34. The casing 33 is provided in one side with a slot 35 and the arm 31 projects through this slot, and is secured to the ring 34.

lVithout being' provided with a lock the structure above described would allow the ring 34 to swivel within the casing 33, so that the arms 3l and 32 could be moved apart or put together at will. Vhen such arms 31 and 32 are projected over a part of the automobile and closed in on the robe, it is then desirable to lock them in that position, and this is accomplished by means of the following structure:

The casing 33 is provided with a recess 36 for a portion of its circumference, in which recess is pivoted a spring pressed ratchet bar 37 arranged to engage a small dog 38 projecting through the slot 39 in the ring 34. lV hen the dog 38 is in engagement with the ratchet bar 37, the members 33 and 34 are of course, locked against relative movement and this would hold the arms 31 and 32 stationary with respect to each other for the purpose of locking the robe in the manner indicated above. This normal locked position is maintained by means of two disks 40 and 41 fitted inside of the ring 34 so that their outer circumferences engage the dog 38 and normally hold it extended into engagement with the ratchet bar 37. Such disks 40 and 41 are, however, provided at` one point with notches 42. These are of such a depth that when brought adjacent the dog 38, the pressure of the spring against the ratchet bar 37 will, when the members 33 and 34 are swiveled with respect to each other, force the dog 38 through the slot 39 and into the notch 42. This will release the dog 38 from engagement with the ratchet bar 37, whereupon the members 33 and 34 and incidentally the arms 31 and 32 will be free to be moved relative to each other in the manner indicated.

It will therefore, be apparent that the application o-f my improved combination will be to control the position of the disks 40 and 41 whereby the dog 38 will be engaged or disengaged with'the ratchet bar 37. This is accomplished as follows: The disks 40 and 41 are turnable around the notched combination detector 43 which is of the same construction as the detector 2, being provided on its front face with notches 44 and a blank space 45. The lock pin 46 projects Vcentrally through the detector 43 and is provided with the operating knob 47 and the y projecting finger member 48. The disks 40 and 41 are separated by a Washer 49. On

the outer face of the disk 41 are two spaced pins 50 and 51, and on its inner face is a pin 52, and on the inner face of the disk 40 is a pin 58 arranged for an engagement with the pin 52.

Assuming now that the combination is broken and the disks 40 and 41 are in that position which holds notches 42 out of register with each other, the combination is operated as follows: The knob 47 is operated to turn the pin 46 so as to bring the nger member 48 on to the blank space 45. Such nger member is then turned to the left to traverse one of the notches of the detector 43. In doing this it engages the pin 51 and moves the disk 41. Simultaneously therewith the pin 52 engages the pin 53 and moves the disk 40 to bring its notch 42 adj acent the dog 38. The linger member 48 is then moved in the opposite direction, rst onto the blank space and then two notches to the right. In this operation it engages the pin and moves the disk 41 in the opposite direction, which action brings the notch 42 on such disk 41 adjacent the dog 38 and into register with the other notch 42. Thereupon, the dog 38 drops into these notches and releases the members 33 and 34 from locked engagement.

It will thus be seen that my improved combination can be applied as well to the form of the device shown in the Fig. 4 as to that shown in Fig. 1.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the object of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as and combination disks V pin movable over do not form a departure from, the spirit of the invention as dened by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A combination lock comprising a casing a pin mounted for turnable and longitudinal movement within the casing, a notched detector surrounding the pin, a Enger member on-the pin movable over the detector,

operable by the iinger member.

2. A combination lock comprising a casing, a pin mounted for turnable and longitudinal movement within the casing, a notched detector disposed around the pin and having a blank space and a recess, a plurality of disks disposed around the notched disk and provided with recesses arranged to be brought into register with said rst named recess, a finger member on the the notched detector and arranged to engage the other disks whereby all the recesses may be brought into register with each other to allow the finger member to be moved therein.

3. A combination lock comprising an annular detector having a blank space and a plurality of notches on its inner face, the blank space indicating the starting point of the combination and the notches the counting point thereof, a pin turnable within the detector, a spring pressed finger member fixed to the pin and movable over the notches to make a clicking sound whereby the combination may be counted, and combination disks operable by the movement of the nger member.

In testimony whereof I affix my signature.
